What he meant was that we or some of us – computer scientists – at some point like to try things that are not that “legal”. The most of us are “clean”, but some of us are “free time hackers”! Nowadays the hackers are almost away from the 17 years old guy, trying to pen- etrate in some website and so on. They are now adults, with families, cars, pets, holidays and a job. They are professionals earning money for acting as such. Application Security is not only important and essential for the companies and their businesses, technology and employees. Application Security is a macroeco- nomic aspect for the countries.

  • Designing Software Architecture to Support Continuous Delivery and Devops: a Systematic Literature Review
    Designing Software Architecture to Support Continuous Delivery and DevOps: A Systematic Literature Review Robin Bolscher and Maya Daneva University of Twente, Drienerlolaan 5, Enschede, The Netherlands [email protected], [email protected] Keywords: Software Architecture, Continuous Delivery, Continuous Integration, DevOps, Deployability, Systematic Literature Review, Micro-services. Abstract: This paper presents a systematic literature review of software architecture approaches that support the implementation of Continuous Delivery (CD) and DevOps. Its goal is to provide an understanding of the state- of-the-art on the topic, which is informative for both researchers and practitioners. We found 17 characteristics of a software architecture that are beneficial for CD and DevOps adoption and identified ten potential software architecture obstacles in adopting CD and DevOps in the case of an existing software system. Moreover, our review indicated that micro-services are a dominant architectural style in this context. Our literature review has some implications: for researchers, it provides a map of the recent research efforts on software architecture in the CD and DevOps domain. For practitioners, it describes a set of software architecture principles that possibly can guide the process of creating or adapting software systems to fit in the CD and DevOps context. 1 INTRODUCTION designing new software architectures tailored for CD and DevOps practices. The practice of releasing software early and often has For clarity, before elaborating on the subject of been increasingly more adopted by software this SLR, we present the definitions of the concepts organizations (Fox et al., 2014) in order to stay that we will address: Software architecture of a competitive in the software market.

As organizations start to move into an agile development methodology, they start to uncover other processes that can be accelerated, such as delivery by DevOps and testing by Continuous Testing. The acceleration that is set in motion via agile makes it necessary to accelerate the release schedule. In order to ensure a successful release, an organization must adopt continuous testing to make sure the conveyer belt does not break down. The modernization maturity model has these three distinct phases: AGILE Agile software development is a different way of thinking about approaching the challenge of development time.

  • Devops Engineer
    DevOps Engineer The IHMC Robotics group is looking to fill a DevOps position. The ideal candidate is somebody who is excited about bringing our lab up to speed on how to best use modern solutions for making our software development and release process super repeatable, reliable, and painless. This is a full-time position. We are huge proponents of strong software engineering practices, leveraging the philosophies of test-driven development, continuous delivery/integration, agile programming, repeatable deployments, and many others that make managing diverse teams and complex software easier. Specifically, the DevOps engineer we’re looking for is awesome at: • Automation. Of everything. An obsession with making every aspect of the development and deployment pipeline painless, testable, repeatable, and reliable is a must-have. • Provisioning and configuration management using tools like Puppet, Chef, Ansible, Salt, etc. The tool of choice is open to discussion, but being comfortable with a provisioning oriented workflow is a must. • Automated Continuous Integration and Continuous Delivery. As a Java shop, we use Gradle as our build system. We are just now beginning to migrate to a full continuous delivery workflow; our builds are becoming more automated with regards to artifact generation, artifact hosting, and integration with tools like Docker. The ideal candidate would be willing to grow a system like this in to something with high reliability so it can be a cornerstone of our open source software workflow. Being test-obsessed is desired, both for making sure our CI stack is doing its job and making sure that your infrastructure automation is just as well tested.

All rights reserved. www.everestgrp.com EGR-2019-32-V-3071 2019 CONTRACTING FOR AGILE AND DEVOPS The “as-is” state of Agile contracting Only 27% of firms have Existing adoption reported more than 50% It has been nearly 20 years since the Manifesto for Agile Software Development was of Agile adoption across released; since that time, four key values and 12 principles that form its bedrock have software teams been instrumental in revolutionizing product delivery across industries and organizations. However, even after almost two decades, many enterprises struggle to scale up Agile adoption – in fact, it is only the last two to three years that we have begin to see contracts customized to an Agile delivery model. In an Everest Group research with over 150 C-level executives, we found: ⚫ 46% of the respondents reported that fewer than 30% of their software development teams leverage Agile methodology, which clearly highlights scalability challenges ⚫ 31% of respondents reported challenges in contracting for something that is difficult to define ⚫ 22% indicated that they had trouble aligning on the appropriate performance metrics Our research also suggests that more than 80% of organizations consider themselves to have low maturity in Agile delivery. To address these challenges, enterprises are looking to third-party service providers to help them move toward enterprise Agile delivery. EXHIBIT 1 Agile adoption across enterprises Source: Everest Group Over 90% of organizations are using Agile development methods in some shape or form However, less than 20% organizations consider themselves to have high levels of maturity in the use of Agile In its current form, an Agile contract is shaped in alignment with the delivery methodology and generally consists of the components described ahead.
